Be it .know-i1 'that I," J AMES STITT, of the city and county 'of SanK Francisca; State of California, have .f invented an Improved Riding StopperforAnchors; `and I d o hereby declarelthe following description and accompanying drawingA are suiiicicnt to enable any i person skilled in` the arlt or scieneeto which it most nearly appcrtains,fto; make audnsc my said invention l or improvements without Ifurther invention or experi- `'Ihe'naturc oressence; of `my invention consists in the combinatiouand arrangement of the parts of a clutch or devls clawfor* holding the cable of a vessel riding at anchonaparticnlar description of said devlce being given-belw. I

In order tolmore fully illustrate audexplain my i i invention, reference 'is hadto the accompanying draw-v ing lbrmiuga part of this specification, in which-L A represeutsa strong metal bar or rod, which may befjbent' to a U-shape, `so as to bring the two ends parallel, as shown atl l; o r it can be bent at right augles, as most couveuient."" l

A cross-head, B,\is provided with holes at each end,

l l sutliciently large` toallowt-he i opposite arrnsI of thc bar A to passthrougli.tliem, and slide up and down upon them. i i

A. second crosshcad,`1`G, similar to VB, is also arranged so as toxmove upon these arms.

`A block orseriesof blocks, D,y which `may be made of'lndia rubberor otherelas'tic material, is placed between these cross-heads. e

" The` lower cross-head is secured iu place bynuts, b,

l ou the `end f eachof `the arms I, which prevent it from slipping oli' thefarmswhen itreceivcs the strain.

i A rodor bar, E, passes througha hole in the mid# v `dleof each ofthe cross-bars and the elastic blocks,

and issecuredbyfnuts, (l, at the cud above the crossbar B, so that, .when4 thc` `1od is drawn outward, the

A `blocks ot" elastic: material will be compressed, the cross-` head G sliding uponthe parallel arms.

`A `suitable ring o1" link, F, is strongly secured t-o the middle'ofthe bar A, iu `a line with the rod E, to

which a chain or chains, or cable, are' iirmly secured.` f

The lower end of the bar or rod E is formed into a strong ring, j', to which a strong chain, H, is secured. l

'lo the opposite end of this chain is fixed ashort Yiron bar, h-,' which is slotted at its end, in `which -end is pivoted, near its middle, oneend of a rectangular piece of metal, L, the projectingr arm of which is slotted, forming what is known as a devils claw.

' The pivotcdarm of this bar fits into the slot in thc end ofthe barh, both the slot and arm being beveled at the bearing-point, and a ring, i, is arranged to slide along thc bar h, so as to bind t-he arm firmly in the slot.

a wrench, in order to bring the small slot nin positionv to unlock over thel projection lnwhen it is desired to release the anchors cable.

In operation, the anclor having lbeen let go, two or three turns of the anchors 'cable is retained around i the windlass. Tile chains Gr are thenvsecured around the windlass, andy oneV of the links of the anchor-s chai is placed in the slot or devils claw, anda p'in, Z, inserted to keep-it in place, after which the cable `is slackencd between the vwindlass and the devils claw,

thus bringing all the strain upon the stopper. i In this position the ship can ride at case, and, when it 1s -def sired'to release the anchor, the pin l is first removed,

and the ring'a'slippcd away from the opposite arm of diately turn, so as to release thc chain.

Having thus described my invention,

lVhat I claim, and desire to secure by Leiters Iateut is l l l 'Iihe combination of slotted bar It, provided withprojection u, bent and forked bar k, pivoted in h, and the ring t', provided with slot n, to pass the aforesaid project-ion, arranged to operate substantially as described.

In witness whereof I have hereunto set my hand and seal. l Y
